Hi i just put a new computer/brain in my Jeep and it starts but won't stay started. Any suggestions on why this its happening? I changed the spark plugs and wires beforei put the new brain in. Please help. Thanks.

 

most likely its the security system. unlock either the drivers door, passenger door, or tailgate with the key (doesnt matter if theyre already unlocked, just cycle the key in the lock). over time, the drivers door lock cylinder may get worn so thats why you should try the passenger door and tailgate if the drivers door doesnt work.
